The Core Mark Tee is the clearest expression of the Unprompted_ identity — understated on the front, bold and unmistakable on the back.
The front features the UNPROMPTED_ logotype in a crisp, minimal alignment.
The back carries the oversized UN split mark in grey and red, a symbol tied to the brand’s rebellion-first ethos and its roots in anti-surveillance culture.
This UK edition is printed on the Stanley/Stella Creator, a premium organic cotton blank known across Europe for its structure, softness, and ethical production.
Fair Wear Foundation certified and climate-friendly, it brings a premium feel to one of your strongest everyday-wear designs.

Shipping & Returns
>UNPROMPTED_ PROTOCOL
Each piece is created on demand the moment you order—no warehouses, no dusty stockpiles, no waste. That means delivery takes a little longer, but it also means you’re getting something made just for you.
Because every product is printed to order, we can’t take returns or exchanges unless there’s a misprint, defect, or damage. If that ever happens, we’ll put it right. Otherwise, once it’s in production, it’s locked in.
Your choice to back made-to-order gear helps us avoid overproduction and keep the system honest. Respect.
Your order ships from the closest fulfilment
node for maximum speed.
Top-tier fabrics.
Zero shortcuts.
Not happy? We'll make it right.
No automated apologies.
Secure transactions.
Untraceable rebellion.
We ship from the node closest to your signal.
We operate fulfilment partners across the US, UK, and EU.
Your order is deployed from the nearest active node for maximum speed and minimal borders.
If a node is offline or out of stock, the packet (your gear) is rerouted through the next secure region in the network.
Fast. Quiet. Local whenever possible.
We don’t do fast fashion, so every piece is made to order. That means we can’t accept returns for buyer’s remorse.
But if your order arrives damaged, misprinted, or not what you expected — we’ll replace it or refund it. No corporate scripts. Just straight answers.
United States:
3–8 business days after fulfillment.
Canada:
5–12 business days.
United Kingdom & EU:
4–10 business days.
Australia / Rest of World:
7–20 business days depending on location.
Fulfillment time:
Every piece is made-to-order (usually 2–7 business days).
Total estimated delivery time = fulfillment + shipping.
A note from the shadows:
If OptiCorp sneaks in a reroute or a local facility is overloaded, your order may take slightly longer — but it will get to you.
Yes. Checkout is fully encrypted — safer than your search history. We never store your payment details, and the only data we care about is the one stitched into your shirt.
Each product page includes a detailed size guide. Give it a quick scan before checkout — your future self will thank you.
Our blanks are premium, true-to-size cuts across T-shirts, hoodies, and sweatshirts. No shrink-to-nothing fast-fashion nonsense. If you usually sit between sizes, we recommend going one size up for a more relaxed fit.
Yes. Every order includes tracking once it ships. You’ll get a link the moment your package leaves the fulfillment node. We don’t do mystery deliveries — OptiCorp already does enough of those.
You’ve got a small window. Each piece is made to order, so once production starts we can’t make edits or cancellations. If you spot an issue, message us immediately and we’ll do what we can before the machines spin up.
We currently ship to the US, UK, and Canada.
Orders automatically route to the closest active fulfillment node (US or UK/EU) for faster delivery.
We’ll expand to more regions soon — the rebellion is spreading.
Unprompted_ is an independent streetwear project built by humans (and one rogue robot, 404).
Every piece is designed in-house, Made to order, and coded with intention - not mass-produced landfill fashion.
